xAI 发布 Grok 4.7，面向编码与知识工作
Introducing Grok 4.7 | SpaceXAI
xAI 发布 Grok 4.7，称其为面向编码与知识工作最强的模型，速度是同类模型的两倍、价格为其一半。该模型采用更大的基座模型，并用更长的强化学习训练，侧重需要数小时完成的任务，自检与长上下文管理能力更强，同时原生理解 Grok Bot harness。安全方面采用全新防护栈，在 LatchBio 生物安全基准上达到 62.4%，HackerBench v0.3 上仅放行 3.3% 的高风险双用途提示。Grok 4.7 已在 Cursor 和 Grok Build 上线，并通过 Grok API、第三方编码 harness、模型路由器和云平台提供，定价为每百万输入 token 2 美元、每百万输出 token 6 美元，另有输出速度翻倍、价格翻倍的快速版本。

SpaceXAI's most powerful model for coding and knowledge work. Twice as fast, at half the price of comparable models.
Grok 4.7 is our most capable model for coding and knowledge work. It works longer on difficult tasks, checks its own work more carefully, and comes with our best-calibrated safeguards to date. Served at the same price and speed as Grok 4.6, it is highly competitive in its class.
On CursorBench 4.0, which stresses longer-running coding tasks, Grok 4.7 is at the frontier in price-performance.
Model Improvements
Grok 4.7 uses a new, larger base model compared to Grok 4.6. It was trained with a longer reinforcement learning run on a harder mix of tasks, weighted toward problems that take many hours to complete. The model is better at verifying its own work and managing longer context. We also trained Grok 4.7 to natively understand the Grok Bot harness, making it better at conversational tasks and general knowledge work.
* high effort
Grok 4.7 is better at creating documents and presentations. In GDPval and AA Briefcase, AI is asked to work on tasks done by professionals such as lawyers, nurses, and financial analysts. Grok 4.7 improves upon Grok 4.6 on both benchmarks and performs comparably to other frontier models.

Safety & Cybersecurity
Grok 4.7 was built with an entirely new safeguard stack. It is the strongest model we’ve tested on refusals and jailbreak resistance. In dual-use domains like cybersecurity and biological work, it leads on both utility for benign tasks and safe refusal on dangerous ones, topping LatchBio’s biosafety benchmark at 62.4%.
Grok 4.7 balances strong cyber defense capabilities with low refusal rates for legitimate use. It shows the highest safety on HackerBench v0.3, our benchmark for risky and malicious cyber tasks, allowing only 3.3% of risky dual-use prompts through while rarely blocking legitimate security work. We’ve also started giving select cybersecurity partners invite-only access to Grok 4.7’s red-team capabilities for defense research.
Pricing and availability
Grok 4.7 is available today in Cursor and Grok Build. It is also available through the Grok API, third-party coding harnesses, and model routers and cloud platforms.
The model is priced starting at $2 per million input tokens and $6 per million output tokens. We also serve a fast variant with twice the output speed at twice the price.
